Hi,

I am also trying to use contour in my program and confused about the qwt contour program. Do I need to implement some contour algorithm to fill my data with points of (x, y, v) or those points have been figured out by the qwt library? I mean, I have a set of (x, y, v) points but the number of those points is just a few and cannot certainly fill up all the display. And if I am to enter the data, where in the Qwt structure should I enter them?

Any help is greatly appreciated.
